24/7 I'm shooting an 06 Mathews Switchback XT, 28" 66lbs, 410 grain Beman Black Max MFX 400s

However, After conversing with DaveC here a bit, I might have to order a half dozen Easton Axis 340s.

It sounds like 340 might be a better spine for me to shoot fixed heads with and I was alway more confident in my old Axis shafts than I am with the Bemans.
